Most of the people around the world use the mobile phones as their preferred device for communication and the percentage of the mobile phone calls are drastically escalating over the period. The cost of calling from a fixed line to a mobile phone was expensive in the past due to the charges which adds to make the connection between two technologies, the mobile and the fixed line.
The invention of the F2M GSM gateway was a good news for the business category since this can reduce the total cost of fixed to mobile phone calls. A GSM gateway connects to a business telephone system in the same way that a traditional analog PSTN or Digital ISDN line does. A GSM Gateway uses the SIM cards to enable calls directly to the mobile phone network. The mobile phone tariff used in the gateway will determine the cost of calls.
The GSM gateway hub contains normally two or more mobile SIM cards. When the user makes the calls from the fixed phone to a mobile, it will land in one of the SIM card installed in the gateway and then connect to the PLMN network as a mobile to mobile call which will reduce the call rates.
The telecom providers offer this service in two flavors. One offering is, the customer purchases the device with a onetime charge and will be there after charged for the usage. In the other offering the customer subscribes this as a managed service where the provider manages the equipments and the volume of calls landing in the hub. In this case the customer will be charged a monthly recurring fee in addition to the usage charge.
There are different types of GSM gateways in the market which can be used with different fixed line technologies like PSTN, ISDN BRI, ISDN PRI etc. Legitimacy of using these devices is based on the telecom rules and regulations in each country.
